PREPARATION (continued)
WARNING: RISK OF ELECTRIC SHOCK! Ensure the electricity to the wires you are working on is shut off.
Either remove the fuse or turn off the circuit breaker before removing the existing bath fan or installing
the new one.
Before removing your current ventilation fan, verify the wall switch box has the required wires necessary for
this installation. These supply wires are power (black) and neutral (white), as shown in the wiring diagram
below. If you do not see both of these wires, consult a licensed electrician.
Check area above installation location to be sure that wiring can run to the planned location and that duct work can be run
and the area is sufficient for proper ventilation.
Inspect duct work and wiring before proceeding with installation.
Before installation, provide inspection and future maintenance access at a location that will not interfere with installation work.
You may need the help of a second person to install this fan; one person on the attic side and one on the room side.
NOTE: Installation may vary depending on how the previous bath fan was installed. Supplies necessary for the installation of
your bath fan are not all included; however, most are available at your local home improvement or hardware store.
